A) 23
B) 32
C) 12
D) 20
Correct Answer: B
Solution :
Weight of copper oxide = 5 g Weight of copper taken = 4 g \[\therefore \] Weight of oxygen in copper oxide = 5 - 4 = 1g \[\because \] Weight of copper, reacted with 1g. \[{{O}_{2}}=4\,g\] \[\therefore \] Weight of copper, which would react with \[8\,g\,{{O}_{2}}=\frac{4\times 8}{1}=32\,g\]. Hence, equivalent weight of copper = 32You need to login to perform this action.
